eBay did that to me too with a go kart I was selling. It was listed under complete go karts, but they said it needed to be listed under 'go kart frames'.... Even after reasoning with customer support, they took it down... so I posted it again and asked people to just message me and I sold my 'complete go kart' for just cash. Thanks eBay, you saved me some money.
Amazing trike. That's a total death trap and it sounds ballzy.
